UniSlide® B90 Series

The B90 Series UniSlide stage has a body width of 9 inches, slider length of 9 inches, carrying a 400 lbs. horizontal load. The B90 can travel up to 39" with the 9" slider/carriage. The B90 is ideal where a heavy-duty workhorse is required.

B90 Series UniSlides are comprised of an aluminum alloy extruded dovetail base with 60 degree opposing V-type ways. An aluminum alloy carriage that runs in the dovetail ways of the base. Lead screws are constrained and supported with steel thrust bearings and snap ring retainer. The lead screw drive nut is a tension adjustable nut made of Delrin providing low friction, and minimal backlash.

The B90 Series UniSlide is available in 3 models/styles. Seven lead screw pitches are available.

Linear UniSlide Assembly Style/Model Options

The UniSlide Series and the styles below combine to create a complete UniSlide Assembly model. Additional options and accessories can be added (See Options/Accessories). Standard style/model options for UniSlide B90 Series Assemblies include:

Free Sliding Model – The simplest UniSlide Assembly where the slider is moved by hand. This features a linear dovetail bearing for smooth motion.

Screw Drive Models – Slide movement is controlled by a lead screw. There are English and metric diameter lead screws available in 1/2" and 14 mm. Each have different advance ratings.

Graduated Knob Models – The position of the payload is measured by combining the readings from the linear scale and engraved knob or drum dial. Measures position from 0.0001" or 0.01 mm.

There is a motorized version of the B90 Series UniSlide - MB90 Series. Other configurations and sizes are available on the other Series UniSlide Assemblies - A15, A25,A40, A60.

UniSlide Configurations

The basic linear UniSlide is a 1-axis stage. UniSlides can be combined for multiple axes in a wide range of lengths and payload capacities. See Examples for images of various multi-axis UniSlides and combinations that include other Velmex stages.

UniSlide Specifications – Manually-Operated Assemblies

Factors such as size of the motor, size of the payload, travel distance, mounting direction/plane, etc. effect the actual capability of any assembly. Please contact Velmex Application Engineers to configure a system that will meet your exact requirements.

Basic Dimensions for B90 Series UniSlide Assemblies

An array of options and accessories is available for the A60 Series UniSlide Assemblies

Adapter Plates

XY Plates – allow two UniSlides to be converted into an XY motion system. For more specifics and to see the adapter plates in use on a Velmex stage visit the UniSlide Adapters page.

B9000XY Adapter Plate – To mount an B90 Series UniSlide to another B90 Series or to an A60 Series in XY. (The B90 would be the base stage.)

XZ Plates – Allow UniSlide assemblies to be positioned vertically facing in any of four directions. For more specifics and to see the adapter plates in use on a Velmex stage visit the UniSlide Adapters page.

B9000XZ Adapter Plate – To mount an B90 Series UniSlide to another B90 Series or to an A60 Series in XZ. (The B90 would be the base horizontal stage.)

XZ Brackets – allow UniSlide assemblies to be positioned vertically, facing in any of four directions and perpendicular to the X or Y plane. For more specifics and to see the brackets in use on a Velmex stage visit the UniSlide Adapters page.

B9001XZ Adapter Bracket – To mount an B90 Series UniSlide to another B90 Series (up to 18") or to an A60 Series (up to 18") in XZ. (The B90 would be the base horizontal stage.)B9002XZ Adapter Bracket – To mount an B90 Series UniSlide to another B90 Series (21"- 24") or to an A60 Series (21"- 24") in XZ. (The B90 would be the base horizontal stage.) (The A60 would be the base horizontal stage.)B9003XZ Adapter Bracket – To mount an B90 Series UniSlide to another B90 Series (over 24") or to an A60 Series (over 24") in XZ. (The B90 would be the base horizontal stage.)

Platform Shelf – A right angled bracket designed to be used with UniSlide® Elevating Tables. However, they also can be used with vertically mounted UniSlide Assemblies to support a payload. The shelf can be inverted depending on the motion required.

Slider Lengths - Varying length carriages (sliders) can be added to all models of UniSlide Assemblies. Choosing a longer slider reduces the standard travel distance. 9" is the standard slider on the B90 Series. 12" is the optional length available for the B90.

Alternative Knobs – A variety of knob styles can be substitute for the standard knob available on the particular style/model of UniSlide Assembly.

Locks – There are a number ways to lock the carriage (slider) position on UniSlides. They include:
(For details see Motion-Locks page.)

Thumbscrew-on-Lead-Screw Lock (-TL) – An easy method to fix the slider utilizing a simple thumbscrew. The thumbscrew lock increases the overall length of the UniSlide base. This lock type is not available on Rapid Advance models.

Traveling Slider Lock (-TSL) – This lock attaches to the slider to lock the carriage in place. Available on Free Sliding, Screw Motion and Graduated Knob models only.

Right Angle Gearbox – Allows the control knob or wheel to be offset perpendicular to the UniSlide ways. Ideal for tight spaces or applications where access to the end of the stage is limited. Available on A25, A40, A60 and B90 Series.

Way Covers (-WC) – Protect the slider and dovetail base from dust, dirt and grit that could hamper the efficient operation of the slide. Way covers increase slider height and reduce the travel length of linear UniSlide stages. Available on free sliding, screw drive and graduated knob models of the A60 Series Assemblies.

Finishes – Standard UniSlide Assemblies have a brushed aluminum finish. Optional finishes are available at an additional charge and include:

Encoders and VRO™ Encoder Readout – For a high resolution position readout an encoder and Velmex's VRO encoder readout can be mounted to most linear UniSlide assemblies. An encoder, mounted directly to the slider gives a true and accurate reading eliminating lead screw and backlash errors. (Not available on all UniSlide models.) SEE: Velmex Controls on the Encoders and the VRO Readout for additional details.
